WHO Calls for Wider Newborn Screening to Detect Birth Defects Earlier

The global health agency says expanding screening programmes could significantly improve survival rates and long-term health outcomes for millions of children

The World Health Organization has urged countries to expand newborn screening programmes, saying early detection of birth defects and inherited disorders can dramatically improve treatment outcomes and reduce childhood mortality.

According to WHO, millions of babies worldwide are born each year with conditions that can be successfully treated if diagnosed shortly after birth. However, many low- and middle-income countries continue to lack comprehensive screening programmes, resulting in delayed diagnosis and preventable complications.

The organisation recommends integrating newborn screening into national healthcare systems alongside routine maternal and child health services. Early identification of metabolic disorders, hearing loss and congenital heart disease can enable timely medical intervention and significantly improve quality of life.

WHO officials also called for increased investment in laboratory capacity, healthcare training and public awareness to ensure more children receive life-saving diagnoses during their first weeks of life.

Health experts believe expanded newborn screening represents one of the most cost-effective public health interventions, offering long-term benefits for families, healthcare systems and national economies.
